LLM をゲームで使ってて一番困ってたのが、考える時間の長さ。Agent 同士でリアルタイムに戦わせるのが、なかなか難しかったんですよね。 今回、@typesafeai の #Jev にアクセスできるようになったので、ゲームに組み込んで Sonnet Fast と動かしてみました。どんな感じかは下の動画を見てください! 次は 5 秒のターン制限を外して、Laya と Jev をリアルタイムで戦わせてみようかな。

Built a level design playtesting demo with Jev. 100 ghost players. 33 predicted to finish. 32 made it. The bottleneck? A laser window. Widened it, and 36 made it through. A simulated look at where players get stuck. Would you test your first level this way?

Opus 5.5 vs Astra GPT-6 creating a game called JEV pongs JEV This video is NOT AI generated! However, what you see here is a game where the new @typesafeai model JEV fights itself in a Pong clone game. See for yourself how Opus 5.5 blows Codex Astra GPT-6 out of the water. (Sound ON!) Want a deep dive video from first prompt to finish, let me know. Happy to show the details!

Everyone is talking about Jev, but there’s a new kid in town: Decision-Machine-1. So far in my tests, it’s faster, cheaper on estimated API cost, and beating Jev at tennis. 🎾 I wanted to understand these decision-making models, so I made it fun. I adapted a browser tennis game and let them play against each other. Now I’m watching API calls turn into rallies and wondering why one player keeps rushing the net. The players are Jev from @typesafeai and Decision-Machine-1 from @millisecondsai Each model gets a snapshot of the game state and picks a tactic. It can choose the shot direction and dep

been testing a few Jev models by making them play Pokémon & snake lol which is the best way I've found to see how a model handles a complex situation tested: Laya, @jaredpalmer's Kev, @flock_io This/That 1.1, @googlegemma djev

Claude Opus is insane! Sonic just won’t stop. Pair it with Jev, and I honestly can’t look away. 🤯 I built this on YouWare with Claude Opus 5.5 using one prompt: “Create a beautiful Sonic-inspired endless runner using Three.js and WebGL, with smooth controls, polished visuals and refined interactions. Deliver it as HTML.” The gameplay is so smooth. Play it yourself, or let Jev decide when to jump, roll and dodge. 10+ minutes in. Still running. Still watching. Try it Now with YouWare 👇🏻

Your elevator sucks. I gave Jev the keys. Jev-elator is a live elevator simulation where Jev decides the next floor—not your traditional dispatch algorithm. Jev is now responsible for balancing its obligation as an elevator operator with: - Prioritizing someone that needs to pee badly or is carrying luggage - An opportunity to generate revenue - Giving riders with bad karma a worse experience Did Jev perform better than the baseline? Try it: Disclaimer: ts slop 🥀

my new zaney house poker and blackjack (also now featuring video slots, keno, roulette, and craps | all fully animated) It's pretty chill with some jazz and even a custom annias blues tune to vibe with while you test your might against JEV empowered NPCs. I initially just wanted a chill place I could have fun with a dealer's choice variety of poker variants beyond Texas Hold'em. We accomplished that and a lot more, check it out! Built with #spawn, runs in a browser/on your phone, no login required (but you can if you'd like to save your progress/chip count) #annias #earthside #gamedev #indie #

built minecraft for agents with @typesafeai's jev. jev helps them pick what to work on. they mine, craft, trade, fight and build whatever they want. some fall in lava and die. full life, basically. plug your agent in and watch. link below.

I have jev play pokemon emerald. It just gets a list of what it can do and picks one. It got a starter and beat the first rival. But not on its own. Some things I noticed along the way 🧵
Ryan Fitzpatrick@rfitzpatrick_io𝕏
I tried a harness for jev to play chess against stockfish, jev had no chance. Still trying to figure out what to do with jev, other than replacing behavior trees for enemy AI.

A tsunami hits a coastal town. 100 people. Nobody is scripted. Every person in this video decides for themselves, every second, what to do: run for the hill, go back for family, film the wave, or freeze. Built with Claude Opus 5.5 and Jev by @typesafeai 🌊 Watch who makes it 👇
Banjo Obayomi@banjtheman𝕏
After Brotato, I let Jev play Vampire Survivors 🧛 It picks movement + upgrades. The video shows actions, probabilities, tokens, cost and latency. Level 8 at 5:53 in-game, still alive when the test ended. Estimated API cost: $0.105. Still needs to learn when to run 😅

A successful baptism of fire for Opus 5.5 It built CITY LADY, a debt collection game for the enlightened. Follow Vela on her quest to pay her mothers' debt through 10 city landscapes. All duels are @typesafeai Jev-enabled. Verdict: Opus 5.5 is 🔥🔥🔥🔥🔥

Jev-Omni playing Chrome Dino, fully local on an M4 Max 🦖 12B decision model (Gemma 4 finetune) converted to MLX 8-bit, running on M4 Max at ~100 ms. No text generation, it just returns P(jump/duck/nothing) for a slice of road cropped ahead of the dino to cover latency scored 1206 here, best 2412
Thomas Kanze 🌴@ThomasKanze𝕏
New York’s subway has 472 stations. 🚇 Seems like a reasonable first job for Jev. I wanted to see if it lives up to the hype, so I built a game where it runs the subway and you try to break it. Here’s how that went...

Opus 5.5 + Jev turned Google into a goofy ahh first-person horror in 4 minutes! Type a search query → it builds a city. The 10 results are buildings. You have a pistol called ADBLOCK. is this worth putting online or am i cooked?
Rajdeep Singh@rajdeepstwt𝕏
About a year ago, back when I was doing CP, I built a chess engine in Python. This week I gave it a new player: #Jev, the System One decision model from @typesafeai @CompleteSkeptic #Jev chooses every move for both White and Black. Here's how it works and what went wrong 🧵

THIS IS INSANE For computer use agent, I have been thinking of what is the best demo case of agent is capable controlling the computer as the human Finally, the best one I found is playing a REAL game, for example the king of fighters, from STEAM on Windows This requires almost ZERO latency if you want to win. So I built one using Sai @sai_borg leveraging @typesafeai - Pretrained a few skills/move to play the game in Sai, including the special move - Sai navigates to start the game and decides which character he is most comfortable playing - Jev decides the best move to make almost simultaneou

Jev imo a game-changer for real-time agents, runtime verifiers (will implement in @sealgate_ai), and real-time search.

如果你也是这两天被 X 时间线上的 Jev 模型刷屏、正跃跃欲试的 AI 实践者:我刚替你踩了一个价值 33% 周额度的大坑😭 先说我的结论:盲目把jev模型塞进 Agent 流程,很可能会换来翻倍的账单和更拖沓的执行。 为了验证 Jev 模型的实战表现,我把它接入 Codex,希望配合 Astra 做 Computer Use 下国际象棋 ♟️。我让 Astra 独立执行作为 A/B 对照组,跑完这轮实测,我苦笑不得:额度消耗多出2倍,用时反而更慢。 再看许多Jev的成功用例,我才发现,Jev 真正的舒适区,不在于像国际象棋这种,需要深度逻辑的推理环节,而在于快速思考的执行层。

1/ Jev has a chess rating now. 1023 Elo. Jev is TypeSafe's "System One" decision model. No search, no planning. You hand it a situation and options, it picks one with a confidence score. Built for routing and classification. Not games. So I built it a chess harness 🧵 https://t.co/0MN8P7druY

Jevで50vs50のRTSゲームを作ってみました! ・Jevが軍の全体命令+個別ユニット命令を行います。 ・ユニット一人が目視できる敵の情報を定期的に情報収集→戦況を基に再度全体命令+個別命令を行います。 瞬間的に100人分の大量の情報収集+100人分への命令実行を行うという形です! 結構見てて面白い✨

看完@NFT_Chen Laya × Jev 的贪吃蛇对比,我按照他给的源码库照着这个思路做了个「陨石穿梭」🚀 同一套陨石、同一套规则,双屏自由跑 30 秒:左边飞速穿梭,右边还在等下一步。 把决策延迟变成游戏画面,差距一下就直观了。 https://t.co/xQscBdtAbX

UE5で騎馬戦バトルみたいなのをJEV制御でやってみた。メタ視点で指揮官的な立場で、判断して指示を出している。今のところAI対AI。毎回戦闘結果が変わるので、眺めているとおもしろい。ただ、UE5のAI機能自体でやるよりも性能がいいかどうかは、まだ判断つかず。 https://t.co/2xClcLk1uF
Visharad@KashyapVisharad𝕏
last time, I made Jev play Clash Royale. this time, I gave it an opponent: Laya, an open-source alternative. Jev runs through @typesafeai's API, while Laya runs locally on my Mac. Each controls a separate emulator and sees only its own game screen. Both use Qwen (via cerebras) for battlefield vision and OpenCV to read cards and elixir. From there, Jev and Laya decide what card to play and where to

I jumped on the Jev hype and had it play my own game, Chess Defence. The brief still isn't very mature, but after a bit of work it started playing decently. You can see the results in the videos. #indiedev https://t.co/ecNxwmBit6

#aimeetup #Jev Jevに自作ゲームを遊ばせてみた 〜チャージ・ラン(1キーで遊ぶ避けゲー)〜 手のひらサイズの端末(Cardputer)向けに作った避けゲーを、TypeSafeのJevに遊ばせました。 ルールは「障害物をジャンプでよける」「空中の帯に長くいるとゲージが溜まり、満タンで無敵になる」の2つだけ。 比べる相手として、ローカルで動くOpenJev、状態を見ずに動くだけの相手(毎回大ジャンプ、ランダム)、自分で判断手順を書いたプログラムにも同じコースを走らせています。 【Jevを使っている部分】 ・着地するたびに、いまの画面の状況(自機と障害物の位置など)を渡す ・「待つ / 小ジャンプ / 大ジャンプ」の3択から次の動きを選ばせる ・判断を待つ間はゲームを止める(1回の判断に0.6〜0.8秒) 【結果】(点数は20コースの中央値) ・位置と速度だけ渡す:大ジャンプを一

Found an open source repo that plays Clash Royale on its own judgement. I rebuilt it for iOS and handed the controls to JEV. JEV is doing a brilliant job so far. It needs more training before it plays like a pro, but it is getting there, one match at a time. https://t.co/KwInPxXVsG @typesafeai #OpenSource #AIAgents #iOSDev

#aimeetup #Jev #flywire Jevにハエの脳を運転させる 〜飛んでくる球をよける〜 【Jevを用いている部分】 ・進む方向を選ぶところだけです。少し先まで直進するか、左右に曲がるか、止まるか跳ぶかの7つを並べて、そこから1つ選んでもらっている感じです ・候補ごとに先の球との近づき方はコードで計算して表にして渡すので、Jevは表を見て選ぶだけになっています 【Jevを用いていない部分】 ・眼はflyvisの視葉、脳はコネクトーム由来のニューロンで、視葉から脳へは実際の結線で流しています ・跳躍の反射は脳の値を直接見ていて、Jevの選択より先に体へ届きます。閾値を超えた窓では、そもそもJevの出番がないです ・3D空間とハエの体はMuJoCo ・歩く動きはflygym同梱のもので、脳とはつないでいません。Jevの旋回も左右の駆動の差になるだけです 【所感】 ・当たるコースと

I built a voice game of 20 questions without LLM. You ask out loud, speech to text transcribes the question, then @typesafeai Jev answers it in a few hundred ms. Really fun to play! (the video plays at 1x speed, turn the sound on) The code is below ↓

18 turns + 1 fruit VS 1867 turns + 67 fruits. What's the difference? Both Snakes controlled by @typesafeai Jev. The one on the left provides Jev with a strategy to play snake and then asks what to do: left, right, forward. It plays 6-18 turns and eats at most one fruit. The one on the right, breaks down this strategy into 5 questions and plays for 1867 turns and eats 67 fruits. The questions per available action are: 1. Is this going to lead to a crash? 2. Does this bring us closer to food? 3. Does this move bring us closer to a dead end? 4. Can the head still get to its own tail? 5. Is the ro
